Coalinga Range in California. At dawn we could clearly see 7mm and .30 Cal bullet holes at 1000 yards.
While attending the CA Long Range Championship a few seasons back, we had the opportunity to test the performance of a high-magnification (63X) spotting scope in near-ideal conditions (maybe the best I’ve ever witnessed). On the event’s last day we arrived at 5:45 am, literally as the sun was cresting the horizon. I quickly deployed our Pentax PF-100ED spotting scope, fitted with a Pentax SMC-XW 10mm fixed-power eyepiece. When used with the 100mm Pentax scope, this 10mm eyepiece yields 63X magnification. Befitting its $299.00 price, this eyepiece is extremely clear and sharp.
At the crack of dawn, viewing conditions were ideal. No mist, no mirage, no wind. The first thing this Editor noticed was that I could see metal nail heads on the target boards. That was astonishing. As soon as the first practice targets went up, to my surprise, I could see 6.5mm, 7mm, and 30-caliber bullet holes in the white at 1000 yards. No lie…
That’s right, I could see bullet holes at 1000. I know many of you folks may not believe that, but there was no mistaking when I saw a 7mm bullet cut the white line separating the Nine Ring and Eight Ring on the target in view. (I was watching that target as the shot was fired and saw the shot-hole form). And when I looked at the 30-cal targets, the bullet holes in the white were quite visible. In these perfect conditions I could also make out 3/8″ bolt heads on the target frames.
The Human Factor — Good Vision Required
When viewing the bullet holes, I was using my left naked eye (no safety glasses or magnification). I also had a contact lens in my right eye (needed for distance vision). To my surprise, while I could see the bullet holes without much difficulty with my left eye, things were fuzzier and slightly more blurry with the right eye, even when I re-focused the scope. That contact lens was degrading the fine resolution.
Then I invited 3 or 4 shooters to look through the scope. One younger guy, with good eyes, said immediately: “Yeah, I can see the holes — right there at 4 o’clock and seven o’clock. Wow.” Some older guys, who were wearing glasses, could not see the holes at all, no matter what we did to the scope’s main focus and diopter adjustment.
The lesson here — if you have to wear glasses or corrective contact lenses, just that extra bit of optical interference may make a difference in what you can see through the scope. Basically anything that goes between the scope eyepiece and your eyeball can degrade the image somewhat. So… you may be better off removing your glasses if you can still obtain good focus sharpness using the diopter adjustment and focus ring. I did the left vs. right eye test a half dozen times, and I could definitely see small features at 1000 yards with my naked eye that I could not see with my right eye fitted with a contact lens. (I did have to re-focus the scope for each eye, since one had a corrective lens while the other did not.)
Mirage Degrades Image Sharpness and Resolution
The “magic light” prevailed for only an hour or so, and then we started to get some mirage. As soon as the mirage appeared I was no longer able to see raw bullet holes, though I could still easily see black pasters on the black bulls. When the mirage started, the sharpness of the visible image degraded a huge amount. Where I could see bullet holes at dawn, by mid-morning I could barely read the numbers on the scoring rings. Lesson: If you want to test the ultimate resolution of your optics, you need perfect conditions.
Chromatic Aberration Revealed
As the light got brighter and the mirage increased I started to see blue and red fringing at the edges of the spotting disk and the large numerals. This was quite noticeable. On one side of the bright, white spotting disc you could see a dark red edge, while on the other side there was a blue edge (harder to see but still present).
The photo below was taken through the Pentax spotter lens using a point and shoot camera held up to the eyepiece. The sharpness of the Pentax was actually much better than this photo shows, but the through-the-lens image does clearly reveal the red and blue fringing. This fringing is caused by chromatic aberration — the failure of a lens to focus all colors to the same point. Chromatic aberration, most visible at high magnification, causes different wavelengths of light to have differing focal lengths (see diagram). Chromatic aberration manifests itself as “fringes” of color along boundaries that separate dark and bright parts of the image, because each color in the optical spectrum cannot be focused at a single common point on the optical axis. Keep in mind that the Pentax does have “ED” or low-dispersion glass, so the effect would be even more dramatic with a cheaper spotting scope.
If you wonder why top-of-the-line spotting scopes (such as the $2980 Swarovski ATS-80 ) cost so much, the answer is that they will deliver even LESS chromatic aberration at long range and high magnification. With their exotic apochromatic (APO), ultra-low-dispersion glass, a few ultra-high-end spotting scopes can deliver an image without the color edging you see in the photo above.
The Pentax PF-100ED is a heck of a spotting scope. Any scope that can resolve bullet holes at 1000 yards is impressive. But if you want the ultimate in optical performance, with minimal chromatic aberration, you may need to step up to something like the 88mm Kowa Prominar TSN-884 with Flourite Crystal lenses ($2325.50 body only), or the 82mm Leica APO ($3598.00 with 25-50X eyepiece).
EDITOR’s NOTE: The purpose of this report is to show what is possible… in IDEAL conditions. With this Pentax 100mm, as well as a Swarovski 80mm, we can often resolve 6mm bullet holes at 600 yards. But again, that performance requires really good viewing conditions. By 10:00 am at my range, even with the 100mm Pentax at 75 power, seeing 6mm bullet holes is “iffy” at best. So don’t go out and mortgage the house to buy a $4000 optic with the hope that you’ll be able to spot your shots at 1000 yards. If conditions are anything less than perfect, you’ll be lucky to see bullet holes at 500 yards.
The real solution for very long-range spotting is to set up a remote target cam that broadcasts a video picture to a screen at your shooting station. Among the target cams on the market, we recommend the LongShot LR-3. It boasts excellent resolution and incredible range. The LongShot LR-3 target cam is used in major ELR competitions.

7mm (.284) remains the caliber to beat in F-Class Open Division (though some shooters have had success with .30-Cal short magnums.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr and 184gr bullets to competitive velocities.
The straight .284 Win is an excellent cartridge, quite capable of winning F-class matches. However, in most barrels, it can’t push the 180s at 2900-2950 fps velocity levels*. A lot of barrels will top out at about 2850 fps. That’s where the .284 Shehane comes into play.
The .284 Shehane is a slightly modified wildcat that retains the same 35° shoulder as the parent case. However, by blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with 30-32″ barrels using H4831sc, Vihtavuori N560, or Alliant Reloder 16. (That’s with a reasonably fast barrel. Some barrels are faster than others.)
Norm Harrold Won 2018 F-Class Open Division Nationals with .284 Shehane Rifle
Norm Harrold (above) won the 2018 USA F-Class Nationals shooting a .284 Shehane. Norm’s F-Open rig features a McMillan Kestros ZR stock and Bartlein barrel chambered for the .284 Shehane, which has a bit more case capacity than a standard .284 Winchester. Norm loaded Berger 184gr 7mm bullets in Lapua brass. Norm revealed his load in an Erik Cortina YouTube Video.
F-Class shooter Erik Cortina notes that the .284 Shehane has a velocity edge over the straight .284 Win because it holds more powder: “The Shehane has more capacity than the .284 Winchester. Ryan is using 54.0 grains simply as a fire-forming load. Typical load for a Shehane is around 57.0 grains of Hodgdon H4831 SC.” By blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc, with long barrels.
Forum member Jim Hardy has shot the .284 with great success. He tells us: “In my humble opinion, the .284 Shehane is the best balanced long-range round there is — bar none. Here is why:
You have to shoot a 30 Cal Magnum with a 240gr bullet to equal the performance of most 7mm chamberings with the 180 Berger VLD. With the .284 Shehane, you have a .308 bolt face, medium action, and Lapua brass. You use less powder than the 7 mags, and have great accuracy and ballistics even while fire-forming. The .284 Shehane shoots inside the 6.5 AND the straight .284, the .300 WSM, and the .300 Win Mag with less recoil. What is not to love about the 284 Shehane? It is a no-brainer for long range — F-Class or Prone or 1000-yard Benchrest.”
Amazing Accuracy When Fire-Forming .284 Shehane
If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel! Gun builder Ryan Pierce of Piercision Rifles explains: “Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fireforming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.”
Scotland’s Grant Taylor. who used the .284 Shehane to finish third at the 2009 F-Class Worlds in England says the .284 Shehane is “very accurate with superb vertical spreads at 1000 yards. [This] caliber… has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”
.284 Shehane Showcase — Two Special F-Open Rifles
Jason Cohen’s “We the People” patriotic .284 Shehane F-Class rifle. This rig scored second place in its very first match, a 3×20 at 1000 yards in Wyoming.
Here’s another handsome .284 Shehane F-Open rifle. Owner Jason Cohen explained why he chose the .284 Shehane chambering: “The .284 Shehane has a proven record of accomplishments and that is why I have chosen it. I use Lapua brass (6.5-284 necked-up), CCI BR-2 primers, Hodgdon H4350 powder, and Berger 184gr bullets. All these components have been a successful combination that has worked flawlessly[.]”
The barrel is a Blake Machine 1:8″-twist finished at 32 inches. It was fitted to my action by Dale Woolum of Woolum Accuracy. Dale also threaded the barrel for a Woolum Accuracy tuner. This has proven to be a valuable tool in my load development.
The rifle began its life as a Will McClosky Cerus stock. This was sent that to Bryan Blake at Blake Machine. Jason noticed that Bryan had been adding aluminum rails to the front of Cerus stocks to lower the center of gravity and improve tracking. Jason asked Bryan to fit the stock with forearm rails, shown in the photo below. Bryan did all the stock work and fitted the action, rails, and RAD recoil pad.
The .284 Shehane — Accurate and Forgiving Wildcat
Jason explains why he selected the .284 Shehane chambering: “The .284 Shehane is amazing, very forgiving and not temperamental. Straight .284 or Shehane — you cannot go wrong. I run a 184gr Berger at about 2850 FPS and get great brass life in my other rifles. I usually start to consider tossing the brass around 15 firings. Primer pockets start to get a little looser and the brass seems to need more sizing than the newer brass with less firings.”
.284 Shehane Load Development
Load development for me starts with each new barrel. I screw on the new barrel, fire 25 rounds of whatever I have left over and then clean it. I push out to 600 yards and do a ladder test in round-robin format. I start 0.6 grains lower than my last charge that worked. I work up from that reduced charge weight in increments of 0.3 grains. The paper tells the rest of the story. Once I get something that works well at 600 yards I go back in work around that by 0.1 grains. After that I play a little with seating depth and look for a change. I will occasionally mess with the tuner and tighten things up if possible.
.284 Shehane Raffle Prize Rifle for Team USA
This stunning .284 Shehane rifle was constructed as a raffle prize to benefit Team USA members preparing for the F-Class World Championship. This eye-catching F-Open rifle was crafted by Blake Barrel and Rifle in Arizona. This prize rifle features all top-of-the-line components: Borden BRMXD Action, Cerus multi-laminate stock with forearm extension, R.A.D. recoil reduction system (hydraulic-damped buttpad), Bix ‘N Andy trigger, and Nightforce Competition scope. The stainless Blake barrel is chambered for the .284 Shehane wildcat, and sports an F-Class Products tuner on the end.
.284 Shehane Also Shines in 1K Benchrest Competition
The .284 Shehane has won in Benchrest as well as F-Class competition. In 2013, Henry Pasquet won the IBS 1000-Yard Nationals shooting a .284 Shehane. Henry’s Championship-winning rig is shown below. Note the 5″-wide fore-end which is not legal for F-Class. Henry also runs a combo tuner/muzzle-brake.
*Some exceptional barrels chambered in straight .284 Win can reach 2900 fps with the 180s. Ryan Pierce has a 32″ Brux barrel that is delivering 2900 fps with the straight .284. However, Ryan acknowledges that his velocities are not typical: “A lot of .284 Win barrels top out at around 2850 fps with the 180s”.

If you buy one book about Long Range Shooting, this should be it. Based on sophisticated testing and research, this 356-page hardcover from Applied Ballistics offers important insights you won’t find anywhere else. Modern Advancements in Long Range Shooting – Volume II, the latest treatise from Bryan Litz, is chock full of information, much of it derived through sophisticated field testing. As Chief Ballistician for Berger Bullets (and a trained rocket scientist), author Bryan Litz is uniquely qualified. Bryan is also an ace sling shooter and a past F-TR National Champion. Moreover, Bryan’s company, Applied Ballistics, has been a leader in the Extreme Long Range (ELR) discipline.
AUDIO FILE: Bryan Litz Talks about Modern Advancements in Long Range Shooting, Volume 2. (Sound file loads when you click button).
Volume II of Modern Advancements in Long Range Shooting ($39.95) contains all-new content derived from research by Applied Ballistics. Author Bryan Litz along with contributing authors Nick Vitalbo and Cal Zant use the scientific method and careful testing to answer important questions faced by long range shooters. In particular, this volume explores the subject of bullet dispersion including group convergence. Advanced hand-loading subjects are covered such as: bullet pointing and trimming, powder measurement, flash hole deburring, neck tension, and fill ratio. Each topic is explored with extensive live fire testing, and the resulting information helps to guide hand loaders in a deliberate path to success. The current bullet library of measured G1 and G7 ballistic coefficients is included as an appendix. This library currently has data on 533 bullets in common use by long range shooters.
Bryan tells us that one purpose of this book is to dispel myths and correct commonly-held misconceptions: “Modern Advancements in Long Range Shooting aims to end the misinformation which is so prevalent in long range shooting. By applying the scientific method and taking a Myth Buster approach, the state of the art is advanced….”
Bullet Dispersion and Group Convergence
Part 1 of this Volume is focused on the details of rifle bullet dispersion. Chapter 1 builds a discussion of dispersion and precision that every shooter will benefit from in terms of understanding how it impacts their particular shooting application. How many shots should you shoot in a group? What kind of 5-shot 100 yard groups correlate to average or winning precision levels in 1000 yard F-Class shooting?
Chapter 2 presents a very detailed investigation of the mysterious concept of group convergence, which is the common idea that some guns can shoot smaller (MOA) groups at longer ranges. This concept is thoroughly tested with extensive live fire, and the results answer a very important question that has baffled shooters for many generations.
Part 2 of this Volume is focused on various aspects of advanced hand-loading. Modern Advancements (Vol. II) employs live fire testing to answer the important questions that precision hand loaders are asking. What are the best ways to achieve MVs with low ES and SD? Do flash hole deburring, neck tension, primer selection, and fill ratio and powder scales sensitivity make a difference and how much? All of these questions are explored in detail with a clear explanation of test results.
One of the important chapters of Part 2 examines bullet pointing and trimming. Applied Ballistics tested 39 different bullet types from .224 through .338 caliber. Ten samples of each bullet were tested for BC in each of the following configurations: original out of the box, pointed, trimmed, pointed and trimmed. The effect on the average BC as well as the uniformity in BC was measured and tabulated, revealing what works best.
Part 3 covers a variety of general research topics. Contributing author Nick Vitalbo, a laser technology expert, tested 22 different laser rangefinders. Nick’s material on rangefinder performance is a landmark piece of work. Nick shows how shooters can determine the performance of a rangefinder under various lighting conditions, target sizes, and reflectivities.
Chapter 9 is a thorough analysis of rimfire ammunition. Ballistic Performance of Rifle Bullets, 2nd Edition presented live fire data on 95 different types of .22 rimfire ammunition, each tested in five different barrels having various lengths and twist rates. Where that book just presented the data, Chapter 9 of this book offers detailed analysis of all the test results and shows what properties of rimfire ammunition are favorable, and how the BCs, muzzle velocities and consistency of the ammo are affected by the different barrels.
Chapter 10 is a discussion of aerodynamic drag as it relates to ballistic trajectory modeling. You will learn from the ground up: what an aerodynamic drag model is, how it’s measure and used to predict trajectories. Analysis is presented which shows how the best trajectory models compare to actual measured drop in the real world.
Finally, contributing author Cal Zant of the Precision Rifle Blog presents a study of modern carbon fiber-wrapped barrels in Chapter 11. The science and technology of these modern rifle barrels is discussed, and then everything from point of impact shift to group sizes are compared for several samples of each type of barrel including standard steel barrels.

There are hundreds of cartridge types capable of winning in F-Open. For F-TR you can shoot either the .223 Rem or .308 Win, but you have many load options. This article will focus on proven choices, currently used by the top F-Class shooters in the world. Our discussion will analyze cartridge selection based on the four different F-Class sub-disciplines: Open Mid-Range, Open Long-Range, F-TR Mid-Range, and F-TR Long Range.
Click image to view full-screen photo.
Mid-Range F-Open Cartridges
For starters, a .300 WSM is certainly capable of winning mid-range matches but it is not ideal. So what is ideal, and why? F-Class Mid-Range matches usually are usually shot at 300, 500, or 600 yards — or all three. At those distances the 6mm and 6.5mm cartridges rule. In moderate conditions, the 6mm Dasher is unbeatable. Its low recoil along with its super grouping ability and good ballistics make it my number one choice for Mid-Range.
Best bullets for the 6mm Dasher are: Vapor Trail 103gr, Berger 105 Hybrid, 108 BT, and 105 VLD (hunting). Best powders are: Varget, H4895, and Reloder 15.
Choices for Mid-Range in Tougher Conditions:
We all know that conditions are not always “moderate” that’s why something a little bit bigger will save you a “Nine” or two. The 6.5X47 Lapua was designed for 300-meter competition, but as soon as it was released, it was adopted by F-Class, benchrest, and tactical shooters. It offers great ballistics with very low recoil and big “accuracy window”. Lapua makes great brass for it (no surprise there) and Berger makes great bullets: 130gr VLD, 140gr VLD, 140gr Hybrids. Best powders in most barrels are Varget and H4350, I don’t use double-based powders such as Reloder 17 and the Vihtavuori N500 series because of their unpredictable performance day to day (greater temp sensitivity).
The 6.5X47 Lapua necked down to 6mm is also a great option for mid range matches. I was able to easily get 3200 fps with 105 hybrids and H4350.
Choice for Long-Range F-Open Competition
In Long-Range F-Open Class (out to 1000 yards), the big, high-BC bullets rule. If I had to pick one cartridge for F-Class (both mid- and long-range) I would pick the .284 Winchester or one of its variants. The .284 Win is currently dominating in F-Open competition. It offers great barrel life, it is super-easy to tune and its recoil is very manageable. The best bullets for it by far (in my opinion), are the Berger 180 Hybrids. But Sierra’s new 183gr MK bullet (with factory-uniformed meplats) seems to perform very well as does the Berger 180 VLD. Best powders for the .284 Win are H4350 and H4831SC.
Long-Range Only F-Open Cartridge
As much as I like the .284 Win, for long-range competitions I like the .300 WSM even more. If you look at a .300 WSM and a 6mm Dasher side by side, they appear almost identical in geometry — the .300 WSM looks like an “super-sized” Dasher. Both cartridges are currently the “darlings” of long-range benchrest due to their extraordinary grouping ability and huge “node’’ windows. Big accuracy windows allow loads to perform well in different conditions and geographical locations. That’s obviously very important if you travel to compete. The .300 WSM loaded with Berger 215gr or 230gr Hybrids is very tough to beat at long range, and it is currently my number one choice.
The 7mm RSAUM is another outstanding long-range round. It resembles a 6BR on steroids and it is almost as easy to tune. Best bullets for it are Berger 180gr Hybrids, 195gr EOLs, and Sierra’s 183gr MatchKing. Best powders for the 7mm RSAUM are: H4350, H4831SC, and VV N160.
Top Caliber/Bullet Combos for F-TR
In F-TR competition, the choice is clear — a .308 Win throated for Berger 185gr BTLRs and 200gr Hybrids will win in mid-range AND long-range comps. Many championships have been won, and many records set with those two bullets in the .308 Win. To quote Danny Biggs (a two times FTR National Champion) “The 185 BTLR is the best bullet for .308 Win ever made”.
The Berger 215gr Hybrids have been used to win many competitions including recently the 2015 F-Class Nationals. Bryan Litz won both the Mid-Range and Long-Range 2015 Championships using 215s. Bryan’s rifle is shown below:
I recommend chambers throated for the 185/200 grain projectiles over the 215/230 grain bullets. The reason is that if you have your barrel throated out for the 215s or the 230s, you could have a “slow” barrel and max out on pressure before the desired velocity is reached. Optimum freebore for the 230s is too long for the 185/200s, so you would be limited to using only 215/230gr bullets in that barrel.Furthermore, the recoil increase with heavier bullets is substantial, causing the rifle to be more difficult to shoot.
.223 Rem — Not A Competitive Option
I would stay away from the .223 Remington. On paper the 90gr VLD will shoot inside most .308 Win loads even at a 1000 yards. But in reality, on average, the .223 Rem, regardless of what powder/bullet combo is used, cannot compete with the .308 Win. [Editor: The equipment lists at major F-TR matches will confirm Kovan’s conclusion here.]
Conclusion (and Other Options)
This article covers only the (currently) most popular cartridge/bullet combos for F-Class (F-Open and F-TR). As I said in the beginning, many cartridge types are capable of winning but are not listed due to their low popularity, case design, or lack of quality components. All of the above information is based on my personal experience and it is meant to help new shooters choose the right cartridges for F-Class matches. Thanks for reading and good luck — Emil Kovan

7mm (.284) remains the caliber to beat in F-Class Open Division (though some shooters have had success with .30-Cal short magnums.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr and 184gr bullets to competitive velocities.
The straight .284 Win is an excellent cartridge, quite capable of winning F-class matches. However, in most barrels, it can’t push the 180s at 2900-2950 fps velocity levels*. A lot of barrels will top out at about 2850 fps. That’s where the .284 Shehane comes into play.
The .284 Shehane is a slightly modified wildcat that retains the same 35° shoulder as the parent case. However, by blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc. With N560 or Reloder 17 you can go even faster.
Norm Harrold Won 2018 F-Class Open Division Nationals with .284 Shehane Rifle
Norm Harrold (above) won the 2018 USA F-Class Nationals shooting a .284 Shehane. Norm’s F-Open rig features a McMillan Kestros ZR stock and Bartlein barrel chambered for the .284 Shehane, which has a bit more case capacity than a standard .284 Winchester. Norm loaded Berger 184gr 7mm bullets in Lapua brass. Norm revealed his load in an Erik Cortina YouTube Video.
F-Class shooter Erik Cortina notes that the .284 Shehane has a velocity edge over the straight .284 Win because it holds more powder: “The Shehane has more capacity than the .284 Winchester. Ryan is using 54.0 grains simply as a fire-forming load. Typical load for a Shehane is around 57.0 grains of Hodgdon H4831 SC.” By blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc, with long barrels.
Forum member Jim Hardy has shot the .284 with great success. He tells us: “In my humble opinion, the .284 Shehane is the best balanced long-range round there is — bar none. Here is why:
You have to shoot a 30 Cal Magnum with a 240gr bullet to equal the performance of most 7mm chamberings with the 180 Berger VLD. With the .284 Shehane, you have a .308 bolt face, medium action, and Lapua brass. You use less powder than the 7 mags, and have great accuracy and ballistics even while fire-forming. The .284 Shehane shoots inside the 6.5 AND the straight .284, the .300 WSM, and the .300 Win Mag with less recoil. What is not to love about the 284 Shehane? It is a no-brainer for long range — F-Class or Prone or 1000-yard Benchrest.”
Scotland’s Grant Taylor. who used the .284 Shehane to finish third at the 2009 F-Class Worlds in England says the .284 Shehane is “very accurate with superb vertical spreads at 1000 yards. [This] caliber… has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”
.284 Shehane Shines in 1K Benchrest Competition Too
The .284 Shehane has won in Benchrest as well as F-Class competition. In 2013, Henry Pasquet won the IBS 1000-Yard Nationals shooting a .284 Shehane. Henry’s Championship-winning rig is shown below. Note the 5″-wide fore-end which is not legal for F-Class. Henry also runs a combo tuner/muzzle-brake.
Amazing Accuracy When Fire-Forming .284 Shehane
If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel! Gun builder Ryan Pierce of Piercision Rifles explains: “Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fireforming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.”
*Some exceptional barrels chambered in straight .284 Win can reach 2900 fps with the 180s. Ryan Pierce has a 32″ Brux barrel that is delivering 2900 fps with the straight .284. However, Ryan acknowledges that his velocities are not typical: “A lot of .284 Win barrels top out at around 2850 fps with the 180s”.

Ian Klemm, 2017 F-TR USA National Champion, is one of America’s top F-Class shooters, both shooting individually and in team competition. Ian is known for his consistency, smooth gun handling, and an uncanny ability to shoot well even in the toughest wind conditions. In this Vortex Video, Ian and fellow long-range shooter Niles Richardson, reveal some of their competitive secrets, and wind-reading techniques. This video focuses primarily on F-Class competition but Ian and Niles also talk more broadly about the myriad factors that contribute to rifle accuracy. Topics include: match strategies, wind and mirage reading, barrel harmonics, bipods, and optics.
Vortex Nation Podcast Episode 57 Summary
From Vortex: Our original intent was to have just a podcast about the sport of F-Class shooting, but when you get these brainiacs (Ian Klemm and Niles Richardson) talking about their obsession… er… “Hobby” you better believe it’s going to turn into a full on long range shooting information assault to the brain. Fact of the matter is, in F-Class, the only thing that matters is long range accuracy – and when we say “Accuracy”, we’re talking about sub-MOA groups on paper at 1000 yards with .308 Wins. Every single aspect of an F-Class competitor’s game is completely dialed in for long range accuracy.
We talk about the guns, their bipods, wind, mirage, barrel harmonics and the special scopes F-Class competitors need for their rifles. Ian even goes so far as to tell us how much his rifle has moved prior to the bullet leaving his 30-inch barrel. Just a simple equation involving acceleration, terminal velocity, moment of inertia of the rifle and coefficient of friction of the bipod and rifle on the ground.

“The blue plastic barrels that we have to shoot through are the idea of the local police — to ensure that we keep our rifles pointing at the targets!” — David Sharp
Here’s a great story from the other side of the pond — the United Kingdom. Shooting a .308 Win factory Savage rifle, a novice benchrest shooter set two new 1000-Yard UK Factory Sporter Class records with a group barely over three inches plus a 6.756″ four-group Aggregate. The Savage had been upgraded with an inexpensive aftermarket stock and Timney trigger, but was otherwise “as manufactured” — with factory barrel.
At Ingleston, competitors shoot for group size only — so there are no scoring-rings on the targets.
On October 14, 2018 David Sharp had a memorable performance at the Ingleston Range in Scotland. David Agg’d 6.756 inches for all four 5-shot groups, a new UK 1000-Yard record for the Factory Sporter Class. His smallest group measured 3.090 inches, which is also a new UK Factory Sporter record. Great Shooting David — congrats!
Sharp Sets Two New UK Factory Sporter Class 1000-Yard Records
Report by Vince Bottomley
In the UK, long-range benchrest is far more popular than short-range. The UKBRA (United Kingdom Benchrest Association) holds shoots at three venues: Diggle (100, 600 & 1000 yards), Bisley (100 yards only) and Ingleston in Dumfries, Scotland (1000 yards).
The Scottish venue is the UK’s latest 1000-yard facility. It was established just three years ago yet it is already holding well-attended monthly shoots. It is operated by the Galloway Small Arms Club and, as you may imagine, it is situated in the beautiful wild Scottish countryside.
The UKBRA operates under IBS/NBRSA rules for the Light and Heavy Gun Classes but, many of the Scottish members are also deer stalkers and came to the benches with their hunting rifles, so we also run a Factory Sporter Class. Factory Sporter rifles must be the original manufacturer’s barreled-action but a more benchrest-compatible stock may be used or ‘bag-rider’ attachments may be fitted to the butt and fore-end. The barreled-action must however be totally as it left the factory — no re-chambering or throating, though the crown may be re-cut. To discourage potentially dangerous trigger modifications, an after-market trigger may be fitted.
The Factory Sporter Class is very popular and Savage rifles, chambered for the 6mmBR, 6.5-284, and .308 Win are the favored factory-classers. These have produced some remarkable performances over the years, often out-performing custom rifles!
David Sharp is a True Sharp-Shooter
David Sharp is a relatively new benchrest shooter, though he has decades of firearms experience. David started his shooting days wild-fowling and rough shooting with a shotgun over 50 years ago. After retiring, he moved to Dumfriesshire and began shooting again — clay pigeon, wildfowling on the Solway, driven pheasant and deer stalking. As a stalker, David keeps his eye in by shooting targets on a local range using his .308 Mannlicher.
Eventually, the pains of old age began taking their toll and stomping up hills was becoming more difficult. Fortunately, David heard about the Ingleston 1000-yard range and joined the Galloway Small Arms Club in 2016. As a complete novice to benchrest shooting, David relied on the guidance and advice from his fellow Club members and eventually purchased a Savage Model 12 F-TR rifle in .308 Winchester to compete in the Factory Class.
Here’s the view looking downrange. What a beautiful place to shoot…
.308 Win Factory Savage with Choate Stock and Vortex Scope
David’s rifle has some upgrades, as permitted for Factory Sporter Class. The Savage trigger was replaced with a Timney. The Savage F-TR stock was replaced with a Choate Varmint stock fitted with a Sinclair front bag-rider. The Choate’s butt was home-modified to better ride the Edgewood bag. The rifle is fitted with a Vortex Golden Eagle 15-60 scope mounted on a 20 MOA Ken Farrell rail via Vortex rings. Dave shoots off a SEB Mini front rest. As the Mini is lighter to lug around than the SEB NEO (and less expensive), the Mini is becoming popular with UK shooters.
David reports: “My rounds are nothing special — I’m using Sierra 2155 155 grain bullets over Vihtavuori N140 powder and CCI 200 primers. I use Lapua brass (large primer) full-length sized in a Redding S bushing die to give 0.002″ neck-tension.”
Although the Ingleston Range is a beautiful place to shoot, as you can imagine conditions can vary dramatically and it is not known for mild days! However, at 9:00 am on the day of David’s record shoot, it was clear and quite still with the flags barely lifting. The temperature was already 15 deg C (59 deg F). What more could any benchrest shooter ask for?
In the photo of David above, you can just see the four 1000-yard targets in the extreme top right of the picture — up near the tree-line. Note, at Ingleston, competitors shoot for group size only. Hence there are no scoring-rings on the target. However, Vince Bottomley says score shooting may begin at some UK ranges: “This year we have purchased a set of electronic targets. The IBS target face can be inputted so we will now start to shoot for score as scores are registered instantly. Previously, it just took too long to score the targets as well as measure the groups.”

Held July 14-15 at the Original Pennsylvania 1000-Yard Benchrest Club, the 2018 Williamsport World Open attracted a large field, with over 130 competitors. During the two-day event, shooters competed in a four-match Aggregate comprised of one Light Gun Match and one Heavy Gun Match on Saturday followed by LG and HG matches on Sunday. The conditions this year were switchy at best, with light rain Sunday morning preceding the start, and typical Williamsport winds. CLICK HERE for complete results.

Kieffer Dominates Match, Winning Both Classes and Overall
David Kieffer dominated the 2018 World Open. This talented shooter earned multiple titles: Two-Gun Grand Champion, Light Gun Grand Champion, and Heavy Gun Grand Champion. David had a steller performance with a 5.433 Two-Gun Group Size Aggregate. Shooting a 6.5×47 Lapua rig smithed by Mark King, Kieffer won the Two-Gun Overall with 10 Rank points (lower is better). Second in Two-Gun was Charlie Lentz with 47 Rank Points. Third was Charles Loebsack with 52 points. There was a turn-out this year of 130 entries in Light Gun Class (17-lb limit, 10 shots per target) class and 130 shooters in Heavy Gun Class (Unlimited weight, 10 shots per target).
Winning Equipment: Dave Kieffer’s winning rifle was a Mark King built 6.5×47 Lapua using H4350 and 140 grain Berger bullets. This featured a BAT action, Krieger barrel, and Nightforce action.
At Willliamsport, the range drops away beyond the firing line, and then rises up again for the target line and pits. There is even a pond down range. This makes for a very scenic view, but also challenging conditions. The Williamsport range is known for tricky winds, with switches and let-ups. There are several flags between the firing line and the 1000-yard targets. It is common to see them pointing in different directions, adding to the challenge.
New Benches at Williamsport 1000-Yard Range
The firing line for the 1000-yard range went through a complete renovation before the 2018 season. Added were 15 new masonry benches with block bases and concrete/plywood tops. The structure over the benches is completely new as is the concrete pad underneath the benches.

Retired Army Special Forces Sgt. Maj. Walter Wilkinson won two of the four individual 1,000-yard Score titles — for Light Gun and Hunter Classes — at the recent Fifty Caliber Shooters’ Association (FCSA) 2018 World Championships. In addition to his two individual score titles*, Wilkinson was also a member of the winning 4-shooter team.
The FCSA World Championships were held July 5-7, 2018 at the NRA Whittington Center near Raton, New Mexico. There were shooters from Australia, Great Britain, Spain and the USA in attendance. The FCSA 1000-yard matches have four classes: Light Gun, Heavy Gun, Unlimited, and Hunter. In the first three classes, the rifles are normally shot from a machine rest off the bench. Hunter Class requires the shooter to fire from the ground with a bipod. And that’s how Wilkinson shot all his relays…
Remarkably, Wilkinson, who shot his near-“box stock” Steyr HS .50 equipped with factory bipod from the ground in the prone position, posted the FCSA Championships’ highest score, beating out shooters in the Light Gun, Heavy Gun, and even Unlimited Classes.
Beating the Benchresters — While Shooting Prone from Bipod
Wilkinson, a Gunsite instructor from Edgewood, NM, shot a two-day total of 290-10X for the Hunter Score, and his Light Gun Score total of 291-7X was the highest of any shooter in any class — most of whom were firing custom-built rifles from mechanical rests atop concrete benches. Wilkinson also placed fourth overall in the 2-Gun Aggregate, which factors both scores and average group sizes from both classes. Wilksonson’s score wins marks his third FCSA victory in the Hunter Class with his Steyr HS .50 since his first win in 2012, and this year he notched his first Light Gun Score World Title.
The Wicked Whittington Range at Raton
Nestled at the base of the Sangre de Cristo Mountains, the Whittington Center’s 1,000-yard range has notoriously tricky winds, especially in the afternoons. On the first day, Wilkinson shot on the afternoon relays. As usual, switching and swirling winds proved to be a formidable foe for all shooters. Wind coming from behind the shooters was switching from 4 O’clock to 8 O’clock and back again, often changing within seconds. Wilkinson was able to very quickly make wind judgments and adjust his hold accordingly. “I couldn’t do anything wrong,” Wilkinson said. “It was like every time the wind changed, I knew exactly where to hold, and the bullets just kept going where I wanted them to.

Holding Off Right and Left for the Cycling Wind
“The highlights of the day were the last two strings of fire in Hunter Class during Relay 4″, Wilkinson explained. “I shot a 50-2X with a 9.8-inch group and a 49-2X with a 7.9-inch group. The Ten-Ring is right at 1.15 MOA, and when you keep them all in that, it says something about your rifle and your load. During both of those two strings, I changed from holding on the right side of the target to the left side during the string.”
Wilkinson’s .50 Delivered Quarter-MOA Groups During Load Testing
Wilkonson’ Steyr .50-Cal has always been an accurate rig. Back in 2012, when Wilkinson developing loads, the big rig showed outstanding accuracy: “As I was working up a load for the HS.50, I shot groups that amazed me. I was getting groups of 0.214 MOA at 220 yards, and I didn’t know what to think. All the bullets were going in the same hole, and it was like ‘Wow, I’ve really got a rifle that can shoot here’. That stunned Wilkinson: “With my [military] experience with the performance of the same .50 BMG cartridge overseas, I didn’t expect that kind of accuracy out of it.”
Cost of Big-Bore Shooting
Is owning and shooting a 50 BMG caliber rifle expensive? Relatively speaking yes, but one must put it into perspective. Rifles may run from $2500 to $6000, maybe even more for a top of the line custom rifle. (Current MSRP for the Steyr H2 .50 is $5910.00). A premium long-range scope will set you back $1500 to $3000. And while excellent commercial ammo is available, it runs $3 to $5 per round! Most serious shooters start reloading for the rifle as soon as practical, not only for the economics of reloading but also for the ability to fine tune custom ammo for their specific rifle. It’s a very rare match that is won shooting commercial ammo.
*Wilkinson’s FCSA trophies state “Hunter Class Score World Champion” and “Light Class Score World Champion”. NOTE the FCSA also recognizes, for each class, a World Champion for Group size, AND a World Champion for combined Group and Score (Aggregate). Plus there are Championship Trophies for Two-Gun. This gets a little confusing. With other Disciplines there is only ONE World Champion per class, generally the competitor who has the best combination of Group Size and Score.

Today was the final day of the Berger Southwest Nationals (SWN). Two 1000-yard individual matches were scheduled. But the weather gods did not cooperate. Sunday matches were cancelled due to high, gusty winds from the North-Northeast that made it very difficult to handle the large, wood target frames. With concern for the safety of pit workers, match organizers waited until 10:00 am, then canceled the matches. It was a disappointment for some, but all the competitors still enjoyed a great week at Ben Avery.
With the cancellation of Sunday matches, the three individual champions — Sling Division, F-TR, and F-Open have been decided based on the Friday and Saturday results. We congratulate the three new Champions: Bob Sebold (F-Open), Phillip Kelley Jr. (F-TR), and Allen Thomas (Sling).

Wicked Winds on Saturday Challenged Competitors
Saturday’s weather was not kind to shooters. Along with cloudy skies came wind — lots of it. The wind was veering, and gusty — with significant changes in velocity. It was hard to predict the cycles — if they could be called that. Erratic was more like it. Many shots were out in the 7 and 8 rings. One champion-level shooter told us: “That was ugly — I got my clock cleaned”. Another shooter said “I ran out of paper to hold off”. At one point, Team Lapua/Brux/Borden (LBB) waited over 30 minutes to take a shot, hoping to get into a steady condition. The patience paid off. Team LBB shooter Jay Christopherson’s final shot (after the long wait) was a 10.
Above is a view from a spotting scope during the 1000-Yard Team Match on Saturday. During the course of the day, there were many 7s and 8s showing on the targets. One competitor said “the wind was so bad, I was holding off the frame”.
Team Lapua/Brux/Berger shot great in tough conditions on Saturday to win the F-Open Team competition. Second from left is Jay Chistopherson, AccurateShooter.com’s System Administrator. When he’s not shooting, Jay works hard to keep our Shooter’s Forum and content sites running smoothly.
The team announced: “Team Lapua-Brux-Borden pulled off a major win today at Berger SW Natinols. Conditions were very challenging but our wind coach was able to keep up with the conditions. Our rifles shot very flat which allowed us to rack up points and Xs. We have a great team and amazing sponsors: Lapua, Brux Barrels, Borden Actions, Cerus Rifleworks. Team members: Jay Christopherson, Eric Cortina, Steve Harp, Tod Hendricks, Pat Scully, and Bob Sebold. Notably, Bob Sebold also won the 2018 Berger SWN Individual F-Open title, making him a double champion.

Industry Report — Berger, Lapua and Capstone Precision Group
Last year Berger Bullets was acquired by the Nammo Lapua Group. Berger Bullets, along with Lapua Products, SK Ammo, and Vihtavuori Powder, are now distributed in the USA by the Capstone Precision Group. Berger will continue to offer its full line of bullets, plus Berger-branded Ammunition (formerly ABM Ammo). Likewise Lapua will continue to offer its superb caftridge brass, plus Lapua’s full line of bullets and loaded Ammunition. In this video, Capstone’s Director Bill Gravatt explains how Capstone is working to expand the availability of Lapua and Berger products. In addition, Eric Stecker explains how Berger Bullets can increase production significantly, now that Berger is operating in the large Nammo/Lapua facility in Mesa, Arizona.
Today is the last day of the Berger Southwest Nationals. After the cancellation of Sunday’s 1000-yard matches due to high winds, this year’s 2018 SWN concluded with the Award Presentations. We watched as scores of medals — along with heaps of cash and Berger bullets — were handed out. AccurateShooter.com also awarded prestigious Corinthian awards to Nancy Tompkins (Sling) and Rick Jensen (F-Class).

Want to learn long-range benchrest skills from the best in the business? Then head to Williamsport, PA this June. The registration period for the 2018 PA 1000 Yard Benchrest School is now open. This year’s session will be held Saturday and Sunday, June 16-17, 2018, with a “Meet and Greet” on Friday Night. Classes, taught by top 1K shooters, are held at the Original Pennsylvania 1000-Yard Benchrest Club Range, one of the best 1000-yard ranges in the country. The school will be limited to 25-30 students with one instructor for every two students.
Praise from a 1K Benchrest School Grad
Here’s a testimonial from a recent graduate: “I can attest to the knowledge that you gain. I went last year and loved it. Have renewed my membership in the Club and would love to go this year. I would love to take the course again. In the photo above I am in the back row, fourth from the right — sunglasses and blue shirt.” — Bob, Class of 2016
Participants will learn all aspects of long-range benchrest shooting from some of the most skilled marksmen in the country. Much time is spent at the loading bench and on the firing line. Classes cover load development, precision reloading, bench skills, and target analysis. You don’t even need guns and ammo — all equipment and ammunition will be provided.
School instructors tell us: “This year’s benchrest school will be a 2-day weekend event. (There is also an optional ‘Meet and Greet’ gathering Friday evening). The school is a beginner class designed to teach the fundamental skills needed to be competitive at at 600 and 1000 yards. Saturday will be spent in class covering a range of topics including reloading ‘dos and don’ts’, load development and equipment handling. Sunday we will shoot an actual match to see what you’ve learned.”
Cost for the class is $425.00 including lunches on Sat/Sun and dinner on Saturday. Act soon if you want to attend the 2018 school — the school fills quickly. NOTE: To secure your placement, payment must be made in full prior to May 25th, 2018.

Report by David and Donna Matthews
The 2015 IBS 1000-Yard National Championships were held September 4-5 at the Hawks Ridge Gun Club in Ferguson, North Carolina. Attendance was great, with 103 Registered Light Gun shooters and 89 Heavy Gun competitors. After a practice day, the competitors tried on Friday and Saturday to master the unpredictable conditions at Hawks Ridge. The 1000-Yard National Match for 2015 featured a three-target Aggregate for each Division (i.e. six targets total for both classes).
The Hawks Ridge range is quite unique — it’s a very wide-open, over-the-hills range. Conditions constantly change (and change very quickly according to several competitors). The management and membership of this range put on a great event this year. Several shooters said this was one of the best-run National-level matches they had ever attended.
Jim Bauer Won the IBS 2015 Nationals shooting a 6mm Dasher in both Light Gun and Heavy Gun Classes. Here’s his match-winning Heavy Gun. Smithed by Gordy Gritters, Bauer’s Heavy Gun featured a BAT action, Kreiger barrel (in barrel block), Shehane stock, and Nightforce scope.
Bauer Drives Dashers to Victory The Two-Gun Champion and Overall winner was Jim Bauer with 24 rank points. In second place was Robert McMichael with 36 rank points. Bauer shot great in both Light Gun (LG) and Heavy Gun (HG) matches, posting Top 10 finishes in both classes. Bauer ran 6mm Dashers in both Divisions (LG and HG) with Vapor Trail bullets. By contrast, McMichael shot big cartridges — a .284 Shehane in LG and a .300 WSM in HG, using Berger Bullets for both calibers. Top lady shooter was Donna Matthews while Amber Brewer won the Junior Division. John Stecik won a BenchSource Annealing machine for shooting the Best Light Gun Target (50 score with a 3.758″ group). Steve Knight shot the Best Heavy Gun Target (100 with 4.407″ group), to win a Douglas barrel.

The Hawks Ridge Gun Club Range and Facility
The 1000-yard shooting facility is a covered pavilion that has 15 shooting benches located in the rolling hills of Wilkes County North Carolina. The Club has a great Barbeque grill on site, which the McNeil family employed to perfection, delivering an outstanding Barbeque chicken meal on Friday night.
One veteran shooter commented that when you can take 103 of the best shooters in the country and hold a event that had very little to any issues you have accomplished something. Range officials were quick to point out that it took a lot of hard work from Hawks Ridge Club members as well as support from the IBS, the sponsors, and the competitors.
Outstanding Prize Table
Over $20,000 worth of prizes were awarded at this year’s IBS 1000-Yard Nationals. Prizes included: Nightforce scopes, Sightron Scopes, BAT Action, Defiance Action, Baity Action, Shehane stocks, rests, reloading tools, Sierra and Berger bullets, and more. Many thanks should go to Stanley Taylor from Douglas Barrels for his time and energy in acquiring prizes for the match.

Here’s a true “Blast from the Past”, a video featuring our friend Stuart Elliott of Brisbane, Australia. This 2011 video has now racked up nearly 680,000 views, making it probably the most-watched long-range benchrest video ever uploaded to YouTube. The video shows Stuart shooting a 10-shot Heavy Gun string at the Brisbane range, Queensland, Australia, in July 2011. In this example, Stuart elected to “run a condition” with his big, .300 WM Heavy Gun, shooting fast with slight hold-off adjustments as the wind increased during the string. The cartridge is a .300 Winchester Magnum, loaded with moly-coated 190gr Berger VLDs. Stuart has an unusual bolt configuration. After each shot, Stuart removes the bolt completely with his right hand, and then uses the bolt to “shuck” the fired cartridge while loading the new cartridge with his left hand. That sounds awkward, but Stuart makes it all look easy. Stuart runs BRT Shooters Supply, a leading vendor of precision shooting equipment (including March scopes), in Australia and nearby regions.

1000-yard Benchrest competitor James O’Hara set four (4) new IBS Records in 2013. These multi-match Light Gun Agg records were secured with O’Hara’s solid performance at the 2013 Virginia 1000-yard Benchrest State Championship. Here are the new records set by O’Hara in 2013:
During the VA state championships, O’Hara was on fire. All four groups were centered for 50s, with three groups under 3″ and the fourth a 3.715″. That’s consistency.
Target 1- Group 2.996” Score 50.2
Target 2- Group 2.433″, Score 50.1
Target 3- Group 3.715″, Score 50.4
Target 4- Group 2.188″, Score 50.1
Group Average 2.833″, Score Average 50.2
On 1000-yard benchrest targets, the 10-ring is just seven inches in diameter, while the X-Ring is a mere 3 inches in diameter. At the Virginia 1K Championships, James managed to keep all his shots within the seven-inch 10 Ring with eight of the shots inside the 3 inch X-Ring. That is amazing accuracy and consistency. David Goodridge says: “This is truly a remarkable example of superb marksmanship, rifle design, assembly, load development and equipment maintenance.” (O’Hara had previously set a 10-match Aggregate Light Gun World record of 4.5389″ in 2012).

James O’Hara Talks About Record-Setting Rifles and Ultra-Accurate Long-Range Loads
James generously agreed to share his knowledge and experiences on the many facets of IBS 1000-yard benchrest preparation, reloading and shooting techniques in an intereview with Australian David Goodridge. This feature originally appeared in Australian Target Rifle Magazine. A few of O’Hara’s responses have been updated, based on a conversation with James on April 8, 2014.
Goodridge: James on behalf of the Australian LRBR community I would like to congratulate you on your achievements in 1000-yard Benchrest and thank you for [doing this] interview. To begin, could you provide an outline on your background and the reasons or factors that led you to becoming involved in 1000-yard BR at the Virginia Club.
O’Hara: I started short-range Benchrest in 1996 for a brief time and won my first 100-yard IBS match and I was hooked. Loss of eye-sight in one eye put a damper on it and I quit shooting for while, and I started shooting trap to try to switch over to left-handed. It worked and I started to pick up a gun left-handed so I went back to the rifle and built a tube gun.
I tried the local groundhog matches but the rules changed every match. I then found the Reade Range and 1000-yard matches. I restocked my gun with a long-range stock and started 1000-yard Benchrest. Finding I enjoyed the challenges associated with long range benchrest, I began 1000-yard Benchrest competition at Harry Jones Range and White Horse Range, two IBS ranges in West Virginia. I basically started after the year was under way in 2011 and I must say it was a very humbling experience. I soon learned that my previous short range [techniques] were not working.
New scales, a K&M arbor press with a force indicator, led to improvements. Then designing and obtaining reamers to my own specifications led to further substantial improvements, with the end result being that the same loads now seem to work from barrel to barrel.
James O’Hara Equipment Details
Gunsmithing: I do all the work myself, except barrel chambering/fitting is done by Dave Bruno.
Favored Caliber: I use a 6mm Dasher with a .266 neck and a .135 free bore. My load is a 103gr Spencer bullet trimmed and pointed with Hoover tools. Load is Alliant Reloder 15, 33.0+ grains weighed on a GD503 scale, with a CCI 450 primer. Right now I’m jumping the bullet about .006″. Previously, I shot them about .010” into the rifling but it was pulling the bullets or pushing them back.
Actions: For the IBS record groups I used a Bat 1.350” Bat B action in a Roy Hunter Stock. Other actions in use include a 1.530” Bat B and a Kelby F-Class Panda. Barrels: The record barrel was a Brux Heavy Varmint, 1:7.83″ twist, finished at 28″, and fitted with a Harrell’s brake. Stocks: I have two Roy hunter stocks and a PR&T and all track very well. They are balanced at two inches ahead of the receiver. All three stocks are glued with liquid Devcon and are pillared, so they are “glued and screwed”. I think this is the best system. Scopes: The PR&T-stocked rifle has a March 10-60X and the two Hunter-stocked guns have Nightforce 12-42x56mm NXS scopes. Rests: My front rest is a Sinclair Competition model that I modified with a cartridge holder that holds cartridges up by the port. I use the new super slick bag by Protektor and a rear Doctor Bag with leather ears. Scope Mounts: Rings are Burris Signature Extra High (the ones with inserts).
Case Preparation and Reloading Techniques:
My cases are three years old, with close to 100 firings. They are all from the same lot. I anneal the cases dirty to save some work and I anneal every time to have consistent neck tension. I punch the primers out and clean the pockets and run the flash hole uniformer in to make sure there is no carbon build-up. You can use the same tool as you use to prep the new cases. Flash holes are uniformed to .0625″. (Flash holes, “out of the box”, are less consistent than you may think.)
I turn necks to .0102″ with a K&M tool. Some competitors don’t turn necks, but without uniform neck tension you will have vertical. I use a K&M VLD chamfering tool and a Wilson case trimmer for new cases and when I trim fired cases. I use a nylon brush for inside the necks and clean the cases outside with 0000 steel wool using a small power station or a drill to spin them. The cases are sized on a Forster Coax press with a Harrell’s full length bushing die. Priming is done by hand using a K&M priming tool. I throw a “close” charge with Harrell’s bench rest powder measure. That charge goes in the pan of my Sartorius GD503 scale and then I trickle up to weight with an Omega powder trickler.
For bullet seating, I now use the 21st Century Hydraulic arbor press with seating force indiciation. I previously used the K&M arbor press with force indicator — it was good, but the 21st Century unit is more sophisticated, more precise, and easier to read. I have a loading block that is color-coded in the pounds of force needed to seat the bullet. I try to keep rounds in sets of 3-lb seating force settings. Each loaded round is put in the appropriate column (based on measured seating force). All loaded rounds are color-coded to avoid mixing. Leftovers from matches are used at a later date.

I have now made a tool from an old bearing surface comparator. It will contact the ogive of the loaded round and it will check the seating depth while it is sitting on a granite block. Relying completely on the force and feel of the dial indicator allows seating depths to be held to .0005″ (i.e. one-half-thousandth). Compared to others means, this seems a more accurate way to check seating depth.
Bullets are spun on a Juenke machine after they are trimmed on a Hoover trimmer and pointed on the Hoover tool. For the next step, a Tubb Bearing Surface Comparator is used to sort bullets to plus/minus .0005″. I don’t discard any bullets — if I have some small lots of bullets that have a shorter or longer measurement they are used for testing. With the Spencer and BIB bullets there are not many that are not within plus/minus .001”. I quit weighing cases because of the outside variations. I only do what makes a difference [on target] and I only test and do load development at 100 yards, where I can control the conditions.
Barrel Freezing (Cryogenic treatment)
For the 2013 season, I cut barrels back to 28″ and had them “frozen” (cryo-treated) at Cryo Plus. I think that both barrels are average in the wind, but the first shot from a clean barrel is in the group. I shot around seven 100s with my other Light Gun. In Heavy Gun, I even won the group Aggregate at the Virginia State shoot. I have cryo-treated all of my barrels and I believe I have proof that it does produce benefits. I talked to George Kelbly about this before I did it. My results agreed with what George had indicated: fire cracking was less, chambering was easier and the major benefit was that the groups did not ‘walk’ as the barrels became heated.
Bench Set-up and Shooting Procedures
I use a spotting scope to help see the flags and the mirage. The mount is a Sinclair for the bench. This really helps because I can’t see the flags far out. I think the most important part of the set up is getting the gun to track, it has to come back in the box every time and shooting under the same condition every shot. I know everybody likes to run them — I do if the condition holds — but if it doesn’t you must pick them one at a time. This is where the direction and the speed of the wind come into play; you must shoot in the same condition you zero in.
When I set up to shoot, I line up the gun on my target and I move it back and forth till I can get it coming back in the ten ring and then I set my scope. I load my record rounds in my holder and I use my sighters out of the box. I now am watching and timing the conditions and I now make the decision of the one I will use and this is the only one I sight-in with. If I have some big guns beside me with brakes, I will wait till they are done or try to get in between their shots (this doesn’t always work).
Trigger control is a must and you have to be consistent. I will give up a perfect sight picture for a perfect trigger pull. I use free recoil and only my finger is on the trigger. After the rifle recoils back, I hold the fore-arm and open the bolt — you have to be careful not to upset the gun in the bags. After loading the next round, I close the bolt and push the gun forward with my right hand on the fore-arm. I am guiding [the stock] forward in between the bags. This gives me less chance to make a mistake, and maybe half of the shots need no or very little adjustment. I know it’s hard to get accustomed to, but try not to take your eye out of the scope so you are watching the mirage and not to get caught in a change. For the best part, I shoot free recoil and do all my testing at 100 yards in my backyard range. I zero dead on at 100 and come up 24 minutes for 1000 yards.
Bore Cleaning Procedures
I never try to get the gun super clean at a match, I like to see a little gray on a clean patch. I don’t want the barrel to be squeaky clean — I like to see a little haze on a patch. When it’s like that, after one fouling shot, the next shot usually goes right where it’s supposed to. When it’s squeaky clean, it may take five shots to foul in.
I used a product called WartHog 1134, and it has served me well for a long time but now that the Hazmat stopped the shipment of it, so I went to over-the-counter products and all are equally bad compared to what I had used but they do the job, it just takes longer. I never pull a patch or brush back through (across the crown), I go one way only (outward) out and then unscrew the brush or take the patch off at the muzzle. I use a 50/50 mix of Hoppies and Kroil after I clean. Just before I shoot I run a smaller patch down the bore to leave a very thing film of oil in the bore. I never want to shoot over a dry bore. If you shoot over a squeaky clean, dry bore, you’ll get copper every time.
What the Future Holds for O’Hara
My goal last season was to set the Agg records. Now I only have one more goal — that is the single target group, so I will back off shooting the Heavy Gun. I have three excellent Light Guns and a bunch of barrels to do it… so maybe! I think the greatest enjoyment is the people you shoot with, the common interest is the bond I guess but I wouldn’t change it for anything. — James O’Hara
Goodridge: James, on behalf of all Australian IBS 1000-yard BR competitors, I would like to thank you for your great patience and cooperation in preparation of this article, and for the valuable and interesting insight that you have provided into what is required to achieve success at the highest levels of 1000-yard BR competition. Not that you need it, but good luck for the 2014 shooting season.

While attending the CA Long Range Championship a few seasons back, we had the opportunity to test the performance of a high-magnification (63X) spotting scope in near-ideal conditions (maybe the best I’ve ever witnessed). On the event’s last day we arrived at 5:45 am, literally as the sun was cresting the horizon. I quickly deployed our Pentax PF-100ED spotting scope, fitted with a Pentax SMC-XW 10mm fixed-power eyepiece. When used with the 100mm Pentax scope, this 10mm eyepiece yields 63X magnification. Befitting its $299.00 price, this eyepiece is extremely clear and sharp.
Then I invited 3 or 4 shooters to look through the scope. One younger guy, with good eyes, said immediately: “Yeah, I can see the holes — right there at 4 o’clock and seven o’clock. Wow.” Some older guys, who were wearing glasses, could not see the holes at all, no matter what we did to the scope’s main focus and diopter adjustment.
Chromatic Aberration Revealed

7mm (.284) remains the caliber to beat in F-Class Open Division (though some shooters have had success with .30-Cal short magnums.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr and 184gr bullets to competitive velocities.
Part 2 of this Volume is focused on various aspects of advanced hand-loading. Modern Advancements (Vol. II) employs live fire testing to answer the important questions that precision hand loaders are asking. What are the best ways to achieve MVs with low ES and SD? Do flash hole deburring, neck tension, primer selection, and fill ratio and powder scales sensitivity make a difference and how much? All of these questions are explored in detail with a clear explanation of test results.

Emil Kovan Competition History:
Want to learn long-range benchrest skills from the best in the business? Then head to Williamsport, PA this June. The registration period for the 2018 PA 1000 Yard Benchrest School is now open. This year’s session will be held Saturday and Sunday, June 16-17, 2018, with a “Meet and Greet” on Friday Night. Classes, taught by top 1K shooters, are held at the Original Pennsylvania 1000-Yard Benchrest Club Range, one of the best 1000-yard ranges in the country. The school will be limited to 25-30 students with one instructor for every two students.
The Two-Gun Champion and Overall winner was Jim Bauer with 24 rank points. In second place was Robert McMichael with 36 rank points. Bauer shot great in both Light Gun (LG) and Heavy Gun (HG) matches, posting Top 10 finishes in both classes. Bauer ran 6mm Dashers in both Divisions (LG and HG) with Vapor Trail bullets. By contrast, McMichael shot big cartridges — a .284 Shehane in LG and a .300 WSM in HG, using Berger Bullets for both calibers. Top lady shooter was Donna Matthews while Amber Brewer won the Junior Division. John Stecik won a BenchSource Annealing machine for shooting the Best Light Gun Target (50 score with a 3.758″ group). Steve Knight shot the Best Heavy Gun Target (100 with 4.407″ group), to win a Douglas barrel.
